Amazon peatland under siege by gold miners

A recent study reveals that gold mining in Peru's Amazon has dramatically accelerated the destruction of critical peatlands, with over 550 hectares lost in the past two years, releasing 0.2-0.7 million tons of carbon. This rapid expansion, driven by easier access and weak law enforcement, poses significant environmental, social, and governance (ESG) risks, including widespread mercury contamination and the potential release of an additional 3.5-14.5 million tons of carbon from at-risk areas. Such unchecked activity presents material regulatory and reputational risks for companies with operations or supply chains linked to the region, potentially impacting valuations and carbon market dynamics.

Analysis

Gold mining in Peru's Amazon has significantly accelerated peatland destruction, with over 550 hectares lost in the last two years, exceeding the previous three decades combined. This destruction has released 0.2-0.7 million tons of carbon, threatening a critical ecosystem that stores carbon equivalent to forests seven times its size. The rapid expansion is attributed to easier access to remote areas and insufficient law enforcement, indicating systemic governance challenges.

Beyond carbon emissions, mining operations introduce severe mercury contamination into local ecosystems, impacting fish populations and posing serious health risks to communities reliant on river fish. The study highlights that 63 of 219 identified peatland areas are at immediate risk, potentially releasing an additional 3.5-14.5 million tons of carbon. This underscores a dual environmental and public health crisis.

While no specific companies are named, this situation presents material Environmental, Social, and Governance (ESG) risks for investors with exposure to the commodities sector, particularly gold mining, or supply chains linked to the region. The projected increase of mining within peatlands to 25% by 2027, from 9% currently, signals escalating regulatory and reputational challenges. This could impact valuations for companies perceived to have weak environmental oversight or indirect links to such destructive practices.

Key Decisions for Investors

• Investors should enhance due diligence on gold mining operations and supply chains in emerging markets, particularly Peru, to assess direct or indirect exposure to environmentally destructive practices like peatland mining and mercury contamination.
• Consider the escalating ESG and regulatory risks associated with commodity investments in regions with weak environmental governance, as unchecked destruction could lead to stricter future regulations or reputational damage impacting valuations.
• Evaluate the potential for increased carbon pricing or conservation-linked financial instruments, given the significant carbon release from peatland destruction, which could create both risks and opportunities in green finance.
